  • climate control functions are often only available to the front rows of seats.
  • vents with a spot-diffuse function or draft-free ventilation and full-fledged climate controls for controlling the climate function are known for this purpose.
  • a development has now emerged that provides full-fledged air conditioning controls for the rear area, for example in luxury vehicles, with vents in the B-pillar or draft-free ventilation in the headliner.
  • a ventilation device for a motor vehicle is disclosed.
  • An air vent is provided in the roof lining of the motor vehicle.
  • the air vent is visibly arranged in the front end of a roof cross member, with a roof cross member structure including the roof cross member or parts thereof serving as an air duct.
  • the ventilation device is used to indirectly and uniformly ventilate the passenger compartment. A conscious separation between at least two ventilation states indoors is not intended. There is also no distinction between a direct and an indirect direction of outflowing air.
  • a motor vehicle In the DE 10 2014 222 139 a motor vehicle is disclosed.
  • the interior or the people in the motor vehicle should be cooled by means of outflowing air, with air outflow openings being provided on both sides of opposite longitudinal sections of the roof frame in accordance with the number of rows of seats.
  • means are provided which detect that a person is occupying the existing seats.
  • a control system can then be used to provide a flow of air to a person sitting on a seat.
  • an indirect flow results from two air streams moving towards one another. Depending on how these two air flows are directed via throttle valves and air conveying systems, a desired result can be achieved.
  • the DE 10 2015 112 898 shows an air conditioning and ventilation system for a motor vehicle.
  • At least one vehicle seat is provided by means of a roof vent system with at least one roof vent.
  • the roof vent has means that allow the active outflow areas to be segmented. In each segment there is an air supply that acts vertically into the vehicle interior with a selection of climate zones.
  • a large roof vent has a series of openings, which assume an opening state depending on the selected segmentation and the corresponding climate zone.
  • a segmentation to be divided parallel to the direction of travel is also proposed.
  • Lighting is also proposed, which is switched depending on the segmentation set. Together, however, the roof vent and the openings cannot change a direction preset in the respective embodiment variant from vertical or parallel to the direction of travel.
  • a non-directional vertical air supply into the passenger compartment is only realized due to a small amount of air provided.
  • a change in the vertical direction into a flow that runs along the roof lining, for example, is not intended. In this context, the lighting cannot indicate such a condition

  • the air guide element includes an air guide plate, a shaft part and another shaft part.
  • the air guide plate and the shaft parts are arranged in a channel.
  • the deformation amount of the air guide plate is changed by relative movement of the shaft parts to change conveyance paths of air supplied from an opening.
  • the air baffle is not exposed to any side of the cabin as a wind direction is set within the duct located at the rear of the opening. Thus, a feeling of pressure for a passenger can be suppressed.
  • an air conditioning system can be seen as known.
  • the aim is to achieve a reduction in noise by reducing a high-frequency noise generated in a louvered grille installed in a supply opening without increasing the number of parts and the product cost.
  • it is proposed to provide a ventilation duct of a peripheral part of the supply opening installed at the upper end of a roof-side duct and to enlarge it to include a supply opening in which an air stream is blown towards the head of an occupant located on a rear Seat of a vehicle sits.

  • ventilation concepts for full-fledged climate functions in the second row of seats are possible. Holistic, comfort-based climate control is also possible. It is possible to record the thermal comfort of the occupants and to automatically control all air conditioning systems.
  • the air conditioning system since it is coupled to the ventilation device via the supply device, can be used to exercise a desired control or programming of the ventilation device. Any modules present in the air conditioning system of the motor vehicle or coupled to it can therefore interact with the ventilation device.
  • a sensor system can be provided to evaluate the thermal comfort of the occupants.

  • a flow pattern of the air outflow element is specifically influenced.

  • the directional element 25 can be actuated by means of an electrical device, for example an electric motor, with operation being possible, for example, via a climate control of an air conditioning system of a motor vehicle in which the ventilation device 10 is installed.
  • the Figure 6b shows the air outflow element 24 with an arranged directing element 25 as components of a ventilation device 10 Figure 6a in a view from a viewer sitting in an interior area of a motor vehicle in which these components of the ventilation device are arranged.
  • a roof area 14 and part of a window pane 32 can be seen.
  • the directing element 25 is in the Figure 6b shown without a gripping element 42 and is in an upper position so that a flow arrow 12 points in the direction of the window pane 32.
  • a direct ventilation state is therefore set on the window.
  • the Figure 6c shows the air outflow element 24 with an arranged directing element 25 as components of a ventilation device 10 Figure 6a in a view from a viewer sitting in an interior area of a motor vehicle in which these components of the ventilation device 10 are arranged.

  • the diamond-shaped locking element 26 is delimited in the visible area to the outside by a surface (outlined by a line in the figure), which bulges into the interior of a motor vehicle, not shown.
  • This convex course can be adapted to the immediate surroundings of the interior of the motor vehicle in such a way that a smooth transition from the immediate surroundings to the locking element 26 occurs.
  • this is indicated (relative to the image plane) in the upper left area, in that the arcuate line essentially represents an extension of an outer line from the roof area 14 shown at the top left.
  • the locking element 26 is shaped in the visible area in such a way that a substantially flat transition from the roof area 14 to an outer surface of the locking element 26 is achieved.
  • any other geometric shapes of the locking element 26 are also conceivable, which make it possible to enable a direct or indirect air flow.
  • the aforementioned features can also occur or be taken into account with a different shape or only a slightly changed shape.
  • the interaction between the course of the roof area 14 and an outer surface of the locking element 26 can be taken into account. It can be seen in particular how the air outflow element 24 and the directional element 25 together cause a desired flow pattern of an air stream to be established from within the ventilation device 10 into an interior area of a motor vehicle, not shown.

  • a roof area 14 is shown schematically. This roof area 14 arches in relation to the image plane above two seat elements 16, which are also shown schematically.
  • a directional element 25 is shown schematically on the left side above the seat element 16, which in this Figure 8 is shown as an arrow pointing downwards. This directional element 25 is in an extended state, so that the portion of the roof area 14 located immediately below curves downward.
  • the installation of the directing element 25, which in this case can also be referred to as an actuator, requires that a change in shape of a roof lining occurs above this seat element 16, which is located on the left side, in order to achieve a targeted influence on the air flow by means of the To enable directing element 25 or the actuator.
  • the directional element 25 can be folded out of the roof area 14 in order to bring about a desired ventilation state.
  • a direct ventilation condition results, which can also be referred to as direct flow.
  • a reciprocal, alternating air flow can be established or achieved on the left and right of the motor vehicle, which is reminiscent of air flows in a natural environment.
  • the air outflow elements 24 on the left and right sides can, for example, be directed towards one another, so that the two competing air flows can cause air turbulence, so-called air rollers, in the center of the vehicle, which are perceived as pleasant by a passenger or generally by an occupant because their direction cannot be assigned and the speed is not constant.
